One of the greatest truths in Scripture is that while God is sovereign, He is also a respecter of order and orderliness. He does not operate in confusion, randomness, or disorder. Heaven itself is structured, with the entire heavenly system arranged in hierarchy from the Father, Son, Holy Spirit,  through the twenty-four Elders, four Living Creatures,  the Archangels, Cherubim, Seraphim and Partriarchs, Prophets, Martyrs, Saints, those who've washed their robes in the Blood of the Lamb and the entire Heavenly Host. God's dealings with humanity reveal a divine system—a sacred protocol.
